RGB values to replace color

Hi all !
I'm quite new on resolve and I wonder about a point:
I would like to modify the color of a part of the image.
After an HSL process, I would like to give RGB values to the new color.
Is there a way to do that ?
For now, I can't see it...

I wish it was that simple but you cant just type in an RGB value but if you right click on the viewer there is a toggle to display your RGB values. You can then point the cursor at the bit you want to change and then use the grading controls to move the image that direction.
